I've got 3 and one has close to 20,000 BP reloads down the bore. Runs Fast and Slow
The key is: cartridge COL and adjusting the right cartridge carrier for that particular reload. In 2 of the Rossi's, only 454120 Long Colts and the 3rd is a 38 Spl modified to shoot 32-20's

I bought 3 just in case they are discontinued. Have been using only one going on 5 years now

Jack, read Irish Ike’s post ... I pan lube mine the same with no excess lube on the bullets, only in the lube grooves.
Change your lube too ... 40-40-20 mix of tallow, paraffin and beeswax. You need the paraffin to stiffen up the lube.
The recipe works for black powder and smokeless reloads including in a 220 Swift at 2800 FPS with lead bullets and no leading
The recipe comes from a 1943 NRA magazine article used for factory loads, pre 1900

Tell us the ingredients of the lube you are using to pan lube and how you pan lube. I have over 7000 BP pan lubed bullets in inventory for multiple calibers and the only BP lube on them is in the grooves. Believe both issues are why you have excessive lube in the seating die(s)
Using a lube sizer and buying the costly H&I dies can if not used properly will put excessive lube on the bullets too

Video ... how to hold and shoot a double barrel shotgun with 2 triggers ...
Note the distance of the 2nd finger from the back of the guard and the thumb rapped around the stock at the bottom of the tang.

Roper - look at the pictures of the ranges re: block walls... https://cjrpc.org/?
* The long range & general purpose ranges are separated by side wall block
* Not clearly shown,( look closely to the right in the picture ) but the 11 pit walls are separated by side wall blocks
None of the walls are covered to prevent splatter
Yes. The targets on the long ranges are in the middle of the ranges. In the pits, the targets are placed directly straight to the back dirt berms to prevent splatter and angled bullets impacting the walls
Both tables in the pit ranges are up against the side walls with a substantial distance back from the firing line
None to speak of but there are always club members that can't shoot directly to the targets in front of the back berms
Suggestion: On the side walls of each berm and range - mark the distance from the firing line in increments to the back berms

The SASS software doesn't agree with this quote from you:
* Initial thread post = Posted Wednesday at 04:36 PM May 20, 2020
* Per your profile - last visit to the Wire was Friday at 11:16 PM, May 22, 2020 ... when I posted your timeline on Posted Sunday at 11:42 AM
* Elapsed time - Wednesday to Friday = 3 days and not one further word of further explanation 'exactly' where the 2nd finger is with all the subsequent posts, including up to Sunday
Too help us all help you, go back to PaleWolfe's trigger guard picture on Saturday and tell us 'exactly' where your 2nd finger is respective to the trigger if it is not inside of of it
Might add, all my years of shooting double trigger shotguns, the 2nd - 3rd and 4th fingers are wrapped around the stock removed from the trigger guard with the thumb wrapped on the opposite side of the stock ... completely away from the trigger guard

Personally, as a guide for exposure & deaths attending SASS matches- I would use the severity on a State by State basis...
https://www.livescience.com/coronavirus-updates-united-states.html
And buy and use a Digital Infrared Forehead Thermometer Before the Match .. https://www.amazon.com/Digital-Infrared-Forehead-Thermometer-Children/dp/B085RVD585/ref=sr_1_14?dchild=1&keywords=body+temperature&qid=1590438857&sr=8-14
Normal adult body temperature ...
* The normal body temperature for an adult is around 98.6°F (37°C), but every person’s baseline body temperature is slightly different, and may consistently be a little higher or lower.
*
In adults, the following temperatures suggest that someone has a fever:
at least 100.4°F (38°C) is a fever
above 103.1°F (39.5°C) is a high fever
above 105.8°F (41°C) is a very high fever
Any SASS member with a fever should leave the range IMMEDIATELY and contact their Board of Heath
And every shooter at the match wear latex gloves
